(or 12433)v Thisinventionrelates to machines ior use"in 'applying pressureto shoebottoms and is illustrated herein with reference `to machines for lmeans vsuch as ahutrnentsl for engaging th positioning gages and theregages, especially the sole gages which may oftenl be locatedin the pathof movement of the shoe --as it sinksinto the pad, rubbing against theshoe cement attachingsoles tovshoes.

Machines of the type referred to areusnally provided vvitha yieldablesupport v"such as a rubber pad for `receiving a sole and'shoe and withand the `last therein` and either pressing isoie and' shoe forcibly intothesnrface of the pador `positivelysupporting them against pressure apeplied by movement ofthe pad, for example, by. inflation' of the'pad orbodily movement `thereof toward the sole and shoe; In either case' thesole and shoe are causedto sink or be depressed into the yieldable4surface of thelpad through relative vmovement of the latter and theshoe, the' distance which `the sole and shoe sink being vari- `ableanddepending upon the operation heimgperformed and the size oi theshoebeing operated upon.

Many machinesl for applying pressure to'rshoe Ybottoms, such as solelaying, sole leveling and cement sole attaching machines,` are 'providedwith mechanism for relatively positioning the sole and shoe on the padbefore pressure is plied thereto. This mechanism "msnallyy come prisessome sort of gages f engaging respe` 'tively the edge face of the soleandthe opposite sides of the shoe and moving `these members laterallyrelatively to each other until the proper positions are attained, thereusually being itujr `'ther mechanism for actuating the gages andiormaintaining them positively in operative engage* ment with the sole and'shoe at least until sufficient pressure has been applied to preventdis-V placement lthereof `from their properrelative positions.

and damaging the shoe upper by marks or scars. `An important object ofthe present invention is to provide improved positioning means in`machine yo1 the type referred V"to whereby fall.

fe shoe danger of damaging the 'shoe upper in this manner' will beeliminated. y.

To this end l have provided, vfor `use with a yieldahle pad and meansfor causing a shoe 'and sole tousinlr into supporting surface oi the padto apply pressure to the sole and shoe, im

proved means for positioning the 'sole'ony the pad constructed andarranged to bend While main-` tainediin operative engagement with thesole and thus move or sini; into the surface of the pad with the soleand shoe. Asl illustrated herein, the improved positioning meanscomprises a pair v of'sole gages arranged for equal'and opposite lat--`eral movement, toward andy from a sole,` on the gages being carried by'Iiexible or resilient arms which permit the arms to bend under pressureand allow the gages to move in aheight- Wise direction Withthe sole andshoe when pressure isapplied" thereto. 'ln this the soie y gages are'prevented fromengaging the shoe 11p-f:

but with the sole.;`and shoe under pressure.

The invention is illustrated herein by Way of example with reference toa machine forcement attaching soiesto shoes such as that disclosed inLetters Patent of the United States No. 2,047,185, granted July 14,1936, in the name of Milton H. Ballard et al., and more particularly theinvention is disclosed as embodied in a pad box of the type shown inLetters Patent of the United States I No. 2,005,755 granted June 25,1935, in the namev of Francis J. Better. It is to be understood,however, that the invention is not intended to be limited in itsapplication or use to cement sole attaching machines or pad boxes of thetypes disclosed in the patents mentioned since, in its more generalaspects, the 'invention is well adapt-v plates I4 and I6, the pad I2being in the form of a closed chamber or bag composed of elasticmaterial such as rubber and being lled with fluid such as Water.

The heel end of the frame lil (Fig. l) is provided at its opposite sideswith vertical guideways (not shown) in which is mounted a slide carryinga rearwardly extending bracket I8, the slide and bracket being arrangedfor vertical adjustment in the guideways as well as for downwardyielding movement against compression springs (not shown) which normallymaintain the slide and bracket in their uppermost positions. At itsupper end the bracket I8 supports a group of horizontal castings orplates 20 two of which are provided with T-slots 22 extendingtransversely of the pad box, only the lower plate being shown in Fig. lofthe drawing. In each of the transverse slots 22 is mounted a slide 24arranged for ymovement widthwise of the pad and provided with aninclined cam slot 26 which is engaged by a projection or pin 28 carriedby each of two pairs of gages, a lower pair 30for positioning the heelportion of a sole A on the pad I2, and an upper pair 32 for engaging theopposite sides of a shoe S on the sole and positioning the shoerelatively to the sole.

As shown in the Better patent, both pairs of positioning gages arepivotally mounted on pins 34 carried by further plates (not shown)located between the slotted plates 20. The gages of each set areinterconnected for equal and opposite swinging movement about theirrespective pivots by intermeshing gear segments 36 formed on the rearportions of the gages. The operation of both sets of gages to move themtoward and from the sole and shoe is effected by movement of thetransverse slides 24 whereby, through the inclined cam slots 26 andprojections 28 referred to, the gages of each set are swung about theirpivots equal amounts in opposite directions. As is also disclosed in theBetter` patent, the slide 24 for the lower or sole gages 30 is caused tomove forwardly or toward the right, as viewed rin Fig. 1, into theposition shown in that figure sure exerted heightwise of the pad.

engagement with the shoe, which is the position shown in Fig, 1, byforward movement of their actuating slide through the manual operationof a swinging frame member (not shown) on the cement sole attachingmachine when such member is swung by the operator into operativeposition over the sole and shoe on the pad box, this swinging membercarrying last and shoe engaging abutments which are operated thereafterto press the sole and shoe forcibly against the pad 4and apply the soleattaching pressure. A fragment ofy the last engaging abutment on theswinging frame is indicated in Figs. l, 3 and 4 by the numeral 38. Bothsets of positioning gages are positively retained or locked againstmovement away from the sole and shoe after they have positioned them onthe pad by reason of the angles of inclination of the cam slots 25 inthe transverse slides 24, these angles being such that the frictionbetween the parts prevents movement of the slides in a direction toretract the gages. As shown in Figs. l and 3, the shoe gages 32 areprovided with end portions l0 which are elongated heightwise of the shoeand are arranged to be retained in vertical slots 42 in the gage arms bycompression springs 44 whereby the elongated members 40 may be quicklyreversed in the slots to adapt them for operating on both large andsmall shoes.

The' sole gages 30 comprise forwardly extending arms or lingers 46rigidly secured to the linterconnected segmental portions 36 of the gagemembers, the arms 46 being of substantial width but extremely thinheightwise and composed of flexible or resilient material, such asspring steel, which will bend readily without breaking under pressureexerted in a direction extending heightwise of the pad. The arms 46 arewide enough so that they cannot bend or flex laterally and,

accordingly, they will operate-positively to engage and position thesole widthwise relatively to the pad and shoe when actuated as explainedabove. As herein illustrated, the flexible arms 46 are secured by'rivets48 in horizontal slots formed in the segmental portions 36 of the gages,al-

though they could obviously be secured to these portions in other waysor could be formed integrally therewith, if desired.

At their forward ends the flexible arms or iingers 4S have secured totheir lower sides by rivets or similar means 50 (Fig. 2) sole engagingmembers `52 which constitute the sole gages proper, these gages beingmuch thicker than the arms 4S but, as shown inFigs. 3 and 4, beingsomewhat thinner than an outsole for small shoes, t

such as childrens shoes. At their inner or work engaging ends the-solegages 52 have forwardly projecting ribs or lips 54 which are providedfor actually contacting with the edge face of the outsole at some pointbetween its inner and outer surfaces and over a relatively thin sectionheightwise thereof, this construction being utilized to help preventforeign matter such as scrapsof leather and so forth getting between thesole gages and causing them to position the sole inaccurately withrespect to the -shoe bottom. On their bottom surfaces the sole gages 52are provided with inwardly extending projections 56 which, as hereinillustrated, comprise thin resilient plates composed of material such asspring steel, which will bend or flex readily under pres- The springplates or extensions 56 may be secured to the bottom surfaces of thegages 52 in any suitable manner for example, as herein shown, by the lspringing away fromv the inner portions thereof,

they are also secured to these inner portions by another screw or rivet'58 (Fig. 2) positionedadjacent to the sole engaging ends of the gages,`

. It Will be seen from the foregoing description that the solepositioning gages 60 at each side of the pad can be moved positivelytoward and with so that the gage members actually engage the edge facesof the sole at relatively thin secn tions heightwise thereof.Theresilient projecthe size of theV sole and even though the gages awayfrom a sole because the gage arms 46 cannot bend laterally due to theirwidth., When the gages move inwardly to engage the opposite edge facesof the sole, only the lips 54 contact theretions or plate 56, however,are always resting on the pad in a position in which theywill partiallyunderlie any sole placed thereon regardless of 52 are in their outer'orretracter position.` Accordingly, the operator places thesole A on thevpad with the heel `portion thereof overlying the projections or plates56. He then actuates the sole gages in the manner described. above tocause them to move at equal speeds toward the opposite edges of thesole, the plates 56, of course, sliding inwardly on the pad fartherunder .the lsole which is then resting lightly on the pad without `a Kshoe thereon. The'lips 54 of the gages 52 engage the sole and, ifnecessary, move the sole laterally of the pad into a properlycentralized position determined by the sole gages.

, The shoe S is then placed on .the sole A; the

opposing surfaces of the sole and shoe in the case of the cementattachment of these members to each other, having been rst treated withcement preparatory to the sole attaching operation.- The operator thenmoves the shoe gages 32, ilil inwardly at equal speeds, as describedabove, until r the end portions 40 thereof engage the opposite sidesofthe heel portion of the shoe atthe widest part thereof, as shown in Fig.3. Since both sets of gages are prevented from moving away from the soleand shoe byreason of the inclined cam slots and projections referred to,the heel portions of the sole and shoe will thus become properly locatedrelatively `to each other and will be held in such position on the pad.The pressure applying abutments, including the heel abutment 38, arenext operated to apply the sole attaching pressure by pressing the soleand shoe forcibly against the yieldable surface of the flexisure,thereby permitting the sole and shoe to` ble pad I2. The pad will yieldunder such pressilient plates or projections 56 become clamped betweenthe sole and pad and thus lock the sole gages positively in operativeposition so that the gages 52 are caused to move downwardly or sink intothe yieldable surface of the pad with the sole and shoe. During thismovement the gages 52 remain in operative relation with the sole withthe thin lips 54 engaging its opposite edge faces, as shown in Fig. 4.The flexible nature of the projections 56 permits them to bend as muchas is necessary in a heightwise direction under the e '3 pressure of`the sole and shoe against the pad. In like manner, the` resilientarms 46will bend as much as is required heightwise of the shoe (as shown inFig. 4) to allow the gages 52 to sink with the sole. and shoe into thesurface of the pad. There mayalso `be al small amount of .tor-1 sionalaction required of the. gage arms 46 about `axes extending lengthwise ofthe arms when the gages 52 are deiiected vout ofva substantially hori-`contal position as they sink into the pad but this I torsional actionwill never be so great but the arms can readily accommodate it-to permitthe gages 52 to sink into the pad While remaining in operativeengagement with the sole. r

The .gages of the present invention, therefore, provide means forpositioning an outsole" on `a `yieldable pad relatively to the bottomvof`a shoe `which is to be pressed against the sole and pad, `which meansdoes not have to be retracted from engagement` with the sole topreventdamaging the shoe upper by rubbing against it and produc-` ingmarks or scars thereon during relative movei ment of the shoe and`pad,whether the pressure-is applied by forcing the sole and shoe intothe yieldable surface of the pad or whether, as in some cases, thepressure is applied by positively engaging the shoe by abutments andpreventing its movement relatively to the pad'while the surface of thepad is distorted byinflation or other-` wise to apply pressure andcause` said surface to wrap itself around thesole and shoebottom' and tobulge outwardly at portions thereof which lie outside the periphery ofthe sole.v VIt will be seen,

" moreover, that the sole engaging lipsv 54; of the gages E52 facilitatethe action'of thegages in sinking into the pad with the sole andvshoebecause they engage only a thin section heightwise of the lyto the planeof the sole las the gages sink into the pad.
